Saving system tutorial / Load through main menu

Questions & Answers
1

Hi all, I’ve been researching ways of saving/loading a game for a few days now and its likely my inability to connect the dots between all the different tutorials out there but Ive come up short in finding a “comprehensive” save game tutorial/system that uses a main menu and a player pause menu together.

I have no problem setting up the UI of a main menu and an in-game pause menu that contains the save button but im struggling to link them together.

What I’ve been looking for is a way of saving a players location, health and what scene they are in etc. and then loading this data from the main menu.

If someone could point me to a tutorial or a free asset (as I’m a broke student) that could light the way for me that would be great! Thanks.

You can save by using PlayerPrefs (not recommended for lots of uses in a short amount of time). I saw The_Icaruz mention it so I’ll mention saving with Binary.

Your script has to have these on top:

using System;

using System.Runtime.Serialization.Formatters.Binary;

using System.IO; IO Standing for Input-Output

    void SaveData()
    {
        BinaryFormatter bf = new BinaryFormatter(); // Create new Binary formatter called bf
        FileStream file = File.Open(Application.persistentDataPath + "/gameInfo.dat", FileMode.Open);   // Create a file stream called file and open the file called gameInfo with .dat extension

        GameData data = new GameData(); // Create Game data called data
        data.highScore = highScore; // highScore variable found in the gameInfo.dat file is now set to highScore variable found in the script

        bf.Serialize(file, data);   // Write the stuff down > take data and write it to data
        file.Close();   // close file > We're not manipulating with it anymore
    }

    void LoadData()
    {
        if(File.Exists(Application.persistentDataPath + "/gameInfo.dat"))   // If the file exists
        {
            BinaryFormatter bf = new BinaryFormatter(); // Create new Binary formatted called bf
            FileStream file = File.Open(Application.persistentDataPath + "/gameInfo.dat", FileMode.Open);   // Open file with name gameInfo with .dat extension
            GameData data = (GameData)bf.Deserialize(file); // Pulling the info out of the file. (GameData) casts it from a generic object to GameData specifically
            file.Close(); // Close the file > We don't need it anymore

            highScore = data.highScore; // Set the script's highScore to the highScore variable found in the data folder

        }
    }

Sorry if the code looks cluttered :). This is a basic version of it working, you can obviously change stuff on it to make it work as you wish to.
